A law of interaction between objects was discovered by Newton in 1687. Any object has mutual attraction force, and the magnitude of this force is proportional to the mass of each object, and inversely proportional to the square of the distance between them.

The law of universal gravitation was first proposed by Newton in his book "Mathematical Principles of Natural Philosophy" published in 1687. Newton used the law of universal gravitation to not only explain the laws of planets, but also pointed out that Jupiter and Saturn's moons also have the same laws of motion around planets. He believed that the moon was not only subject to the gravity of the earth, but also the gravity of the sun, thus explaining the two-dimensional difference, business trips and other long-detected in the motion of the moon. In addition, he also explained the orbit of the comet and the tidal phenomenon on the earth. According to the law of universal gravitation, Neptune was successfully predicted and discovered. After the law of universal gravitation appeared, the study of the motion of celestial bodies was officially based on the theory of mechanics, thus establishing celestial mechanics. Simply put, the greater the gravity produced by the matter, the gravity generated by the matter of the earth is enough to grasp everything on the earth.

Any two particles attract each other through forces in the direction of the connecting center line. The magnitude of the gravity is proportional to their mass product, inversely proportional to the square of their distance, and has nothing to do with the chemical nature or physical state of the two objects and the intermediary substances.

Gravity is considered one of the major basic forces in the universe in classical physics, proportional to mass and inversely proportional to the square of distance. However, in Einstein's theory, gravity is no longer a basic force, but is just a manifestation of the bending of the space-time structure. The reason why the bending of the space-time structure is the huge mass.

According to the theory of general relativity, the space-time around the sun is affected by the huge mass of the sun, forming space-time bending, while the planets move according to their geodesics, which is equivalent to a uniform linear motion in the inertia system.

Each particle in the universe attracts other particles with a force. This force is proportional to the product of the mass of each particle and inversely proportional to the square of the distance between them.

Specifically for cosmic celestial bodies under extreme conditions such as black holes, they have extremely strong attraction. When explaining this attraction, scientists attribute it to space bending. The reason for space bending is the huge mass of the black hole itself.

Quantum mechanics believes that gravity is caused by the exchange of gravitons between two particles.

In the early days, people were able to distinguish many forces, such as friction, gravity, air resistance, electricity and human power. Newton accurately attributed these seemingly different forces to the concept of gravity for the first time: the apple lands, the person has a weight, and the moon revolves around the earth, all of these phenomena are caused by the same reasons.

The reason why light is sucked in by a black hole is because the gravity causes space to be distorted. Light enters the black hole with the twisted space. Everyone knows that light only goes in a straight line. Light is not sucked in by gravity, but light still goes in a straight line. However, space is distorted and enters the black hole. For example, draw a line on paper and twist that piece of paper, it is still a line.

Light travels along a straight line. According to general relativity, space will bend under the action of gravitational field. At this time, although light still travels along the shortest distance between any two points, it is no longer a straight line, but a curve. Fictionally speaking, it seems that light originally wanted to go straight, but the powerful gravity bends it.

The spiritual evasionist believes that gravity is the action between matter. The gravitational field is the result of this action. This result is like a spatial property. It is precisely because of this spatial property that matter has inertia. Moreover, the magnitude of this inertia is only related to the mass of matter. Large mass will determine the magnitude of gravity. This is why gravitational mass and inertia mass are strictly proportional, which is correct. Einstein was also correct to establish the principle of equivalent.

Inertia itself is not a force, it is a property manifested by matter in the gravitational field. Don’t use gravity and inertial forces to make things difficult for you. "Gratility is the source of inertia."

It shows completely different functions at different scales and different particle motions. This is also very reasonable in philosophy.

In physics, gravitational waves refer to ripples in the bending of time and space, propagating outward from the radiation source through the form of waves, which transmit energy in the form of gravitational radiation. General relativity predicts the existence of gravitational waves. The existence of gravitational waves is the result of Lorentz invariance in the general relativity theory because it introduces the concept of limited propagation speed of interactions. In contrast, gravitational waves cannot exist in Newton's classical theory of gravity, because Newton's classical theory assumes that the interaction propagation of matter is infinite.

Gravity is considered an effect of space-time bending. This bending is caused by the existence of mass. Generally speaking, the larger the mass contained within a given volume, the greater the space-time curvature caused at the boundary of this volume. When a mass object moves in space-time, the change in curvature reflects the position change of these objects. In certain specific environments, accelerating objects can change this curvature and can propagate outward in the form of waves at the speed of light. This propagation phenomenon is called gravitational waves.

When a gravitational wave passes through an observer, due to the strain effect, the observer will find that time and space are distorted. When gravitational waves pass, the distance between objects will increase and decrease rhythmically, and this frequency is the frequency of the gravitational wave. The intensity of this effect is inversely proportional to the distance between the sources of gravitational waves. The orbiting two-neutron star system is predicted that when they merge, it is a very strong gravitational wave source, and the huge acceleration generated when they orbit each other. Because they are usually very far away from these sources, the effect when observing on Earth is very small.

Gravitational waves should be able to penetrate places where electromagnetic waves cannot penetrate. So guessing gravitational waves can provide information to observers on Earth about black holes and other strange celestial bodies in the distant universe. These celestial bodies cannot be observed in traditional ways, such as optical telescopes and radio telescopes, so gravitational wave astronomy will give us new insights into the movement of the universe.

Gravitational and gravitational waves drive the transformation and operation of energy in the end of the world. In addition to natural energy, the source of energy is a huge energy source in the underground world.

The mutual attraction of Agula's heart and blood pool is changing the future and destiny of the underground world.
